How to edit the joint locations on an r15 rig after the new update?

I used to use a rig editor plugin, and the joints stay at the locations that I've edited them to be at when I don't use them as a startercharacter but as an NPC. But when I use my edited rigs as a startercharacter, the joints snap back into place. I was just wondering is there anyway to edit rigs so that this doesnt happen after the new "joint" update??
